从错误信息来看，ddtv本身没有出现错误，是网络层面发生了错误。
具体的错误情况是
1、无法连接到B站服务器。
2、连接B站服务器超时。
请确认网络和代理是否正常，网络不稳定，和使用了不合适的代理设置都可能造成这样的结果。

之后会考虑将这类问题封装成更明显的提示文本。

在进行录播的时候，其他直播间均可正常采用FLV模式录播，唯有一个直播间录播异常。该直播间在正常进行直播，录播中途中断，手动重启该直播间录播失败，删除该直播间之后又重新添加该直播间才录播正常。

麻烦提供一下房间号和这一次启动对应的log文件(*.sqlite，如果有同名txt也麻烦一起提供一下)，我确认一下。
ps：另外，更新到Dev版本试一试呢？我在Dev中使用了新的检测接口

用的最新版Dev，日志我晚上找时间发给您，日志用什么方式发送？

从日志中间中看，录制环境的网络状况非常不理想...各种超时和断连，这种情况下推荐HLS模式录制，HLS录制如果是偶尔断连不会影响录制内容。

FLV模式因为需要持续连接，一直重复断开连接可能会出现未知的问题，这些未知问题因为是多重网络问题叠加造成的比较难以复现。
